as usual, on a layer of ashes, the latte-rheing .supported` as "to its outer portion, upon an annular ash pan G which is adapted to receive within its flaringa sides 8 that extends downwardly "frein the shell 1. 'the ash pan (j is mounted for rotation, relative to the shell 1, upon an annular series of supporting rollers 9, 9, upon which travels a 'flange 10' provided by the under side of said ash pan. The central opening 11 of said ash pan, through'ivhich the ashes are discharged as Lhereinafter described, is surrouiuled by] an upwardlyA projecting flange 12, that`""is high enough to maintain a sutlicient depthof .vater in the ash pan rto inalie a traiter seal with the apron 8 of `the shell.' ISaid water also serves to cool :the ash pan 6 and prevent its burning out.

The ashes that underlie the central portion of the fuel bed, above the central open ling` 11 of theashpan, are supported by a `blast distributor 13, here shown in the form tributor has 'its central portion suitably connected by radial Webs lll'yvitha rotatable structure 15 that issupported upon an annular-series of rollers 16. `rthe structure 15, to which rotation Vis imparted at a different that of the ash pan .6, provides au annular Water chatnber 1'? for the recep tion of a circular flange 18 dt-pending from Water' said ash pan,- whereby vto provide a said independently rotatable parts.

The vstructure 15 constitutes, as willbe seen, a conveying device for the ashes that are discluirged` througgh the opening 11 of the ash. pan by thei'ac'tion of a plow 19, as, vindicated in Figs. 2 and 3. Said plow'lll, as shown in 2, rests on thev siirface of the ash'pan 6 and previdesaA plurality of arins or sweeps 20, adapted to. rotate in a clock Wise direction, and so curved that'their movement will force ward the opening,- 11v when the plow is caused to travel faster than said ash pan t3. At their inner ends these arins or sweepsl() the shell 1 is superposed, have upwardly inclined portions 21, which 7 an apron I the ashes inwardly to` serve to raise thef ashes over therange 12,

and to assistin this action, tho@- plow may -also be provided withl additional inclined portions 22,22, for the same purpose. In order to brmg about rotation of the plow relative to the ash pan 6, said plow is prol vvided withan inwardly directed projection :23, which stands in the path of a latch with the blast distributor 13 and relatively.

to the ash pan 6, inlorder to render said low operatlve; and `s\`aid latch member 24 1s adapted to be lowered by said handle 25I when 1t is desired to render said plow inoperative by' rotation in unison with said ash pan, such rotation in unison taking place b reason ofthe pressure of the superposed nel bed, tending to resist any relative movement between the plow and thc ash pan.

The operation of the mechanismV as thus far described is as follows z--The ash'pan G is continuously rotated relative` to the fuel containing shell by means of a pinion 26 that meshes with an annular gear 27 on the bottom of said ash pan, said pinion 26 being secured to a shaft 2S that is connected by gearing 29 with` any suitable source ci power, not sl1own. lRotation in the same direct1on,b ut at a higher speed, is continuous#- lower portion ofthe producer shell.y This ly imparted to the blast distributor 13 by a pinion 30 in mesh with a gear 3l on the member 15, said pinion 30 being secured to a shaft 32 which is driven by a belt 33 from the shaft 28. The belt 33`engages oppositel arranged cone pulleys 34 and 35 `on the shafts 28 and 32 respectively, thus constitutinga variable speed drive between these shafts, which can be manipulatedto secure a greater or less 'speed of rotation for the blast distributor 13.

Underthese conditions, and assuming that the speed of the blast structure is in excess of the speed of the ash `pan 6, the elevation of the latch member 24 will cause the plow 19, Fig.'2, to rotate in unison Withtheblast device, thus crowding the ashes inwardly toward the opening 11 of the ash pan. The inclined portions 21 and 22 of the plow constitute surfaces that cause the ashes to ride upwardly over the flange 12, and as a con- -the purpose' of effecting the final removal of ashes-from the producer through a notch' or the' intermittent discharge oi' ashes from the shell 1. It will be seen that irrespective of whether such discharge be continuous or intermittent2 therate of discharge can be varied at will, simply by increasing or decreasing the amount by which thc speed of the rotating blast structure exceeds the speed of the rotating ash pan. This can readily beaccomplished by changing the position of the belt 33 onthe pulleys-34 and It is also apparent that the mechanism as herein described is susceptible-of a modified m'ode of operation that is predicated upon a greater speed bein imparted to the ash pan than to the b ast structure. Under these conditions, the plow must be constructed'as shown at 40 in F ig. 3with its blades or sweeps 20 and 22 having the opposite curvature from the sweeps 20 and 22 of Fig. 2. The operation of this mechanism, with the blast distributor revolvin at a slower speed than the ash pan, parta (es of all the possibilities hereinbefore descxlfibed 'with ref erenee to both the continuous and intermit.

tout discharge of ashes', and in addition affords a definite advantage in that it tends to more uniform cleavage of the ashes in the is because of the influence of the stationary shell with its depending apron 8 onthe rashes near the outer peri bergf of the ash pan, it'bcing clear that said s ell has a re- IOT) tarding effect on the adjacent ash and fuel,

whiclii, unless counteracted, brings about a olea age at too low a level in comparison to the ideavage 'above the blast distributor 13.

Whenthe ash plan is speeded up, as contemplated by t ense of a plow such 4as shown in Fig. 3, this retarding tendency of the shell can be counteracted, and thus an llO approximately horizontal' and uniform producer can be obtained. Under either ot the above conditions of operation of the structure shownI in Fig. 1, it is preferable to make the edge' of the apron 8 serrated, as shown at 41, Fig. 4, thereby eliminating,

to some extent, the tendency of the ash to-v become acked in the space between said edge and) the bottom of the .ash pan.
